Questions & answers

Can I start a business if I'm an immigrant without a Social Security number?

+

Yes. With an ITIN (Individual Taxpayer Identification Number) you can register your business, get an EIN, and open a business bank account. We are IRS Certified Acceptance Agents (CAA), so we help you apply for your ITIN with Form W-7 and guide you through the full business registration process.

What do I need to register my LLC or business?

+

It depends on the state, but in general you need: a business name, an address, a registered agent, and an EIN. We register your business from start to finish, hand you your documents in order, and explain what comes next: bank account, licenses, and your tax obligations from day one.

Can I qualify for a business loan?

+

We work with loans from $5,000 to $3.5 million. The basic requirements are: a credit score of 600+, at least 6 months in business, and sales of $7,000 or more per month. Pre-qualifying is free and we respond within 24 hours or less. If you don't meet the requirements yet, we tell you exactly what to do to get there.

What taxes do I have to pay as a new business owner?

+

At minimum: federal taxes on your income (and self-employment tax, if it applies), state taxes and, depending on your activity, sales tax. The most important thing: keep your personal and business finances separate from day one and keep your bookkeeping up to date. We handle your tax preparation and bookkeeping so the IRS never catches you off guard.

What is an EIN and why do I need one?

+

The EIN is your business's tax ID number — like a "Social Security number" for your company. You need it to open a business bank account, hire employees, apply for loans, and file taxes. We process it for you as part of your business registration.

What is SAM.gov and why should I register?

+

SAM.gov is the registration that lets you sell products and services to the federal government — real contracts, with guaranteed payment. If your business is ready to grow beyond private clients, we register you and walk you through the first steps to compete for government contracts.
